Title: Process and apparatus for the manufacture of carbon
IPC: C09C1/54
Filed: 1931-04-15
Abstract: <PICT:0377259/III/1> <PICT:0377259/III/2> In the formation of carbon by the catalytic decomposition of carbon monoxide wherein the powdered catalyst is kept in suspension by mechanical agitation, the amount of catalyst supplied is regulated in correspondence with the carbon monoxide introduced.  The gas is fed into the reaction chamber by a pipe 6 into which the catalyst, e.g. ferric oxide, is delivered by a worm 20 from a container 9.  Agitation of the catalyst within the gas p  is effected by paddles 3 spirally arranged on a hollow shaft 2, adapted to be water cooled, and provided with a pulley 8<1> from which the worm 20 is driven through a pulley 8.  By altering the ratios of the pulleys 8, 8<1>, the amount of catalyst delivered can be regulated.  A pressure gauge and a pyrometer 14 are provided whereby the conditions of the reaction can be controlled.  The pulley 8 may be driven from the shaft of a gas meter through which the carbon moxoxide passes.  As shown in Fig. 3, propellers 31 on the shaft 2 are adapted to move the catalyst in a direction opposite to that of the gas current.  Two valved outlets 13<1>, 13<2> are provided for the escape of the reaction products, the outlets communicating with either side of an apertured partition 30 by which the gas in the chamber 1<2> so formed is protected from material projected by the paddles.  By manipulating the valves in the outlets, the rate of discharge of the products can be controlled.  Jackets 33 are provided through which steam may be passed for ensuring a reaction temperature of 425 DEG  C. and a heat-insulating covering 35 may be provided; the jackets 33 may also be used for cooling media.

Title: Telephone circuits
IPC: H04M1/272
Filed: 1973-03-07
Abstract: 1465483 Storage arrangements GENERAL INSTRUMENT MICROELECTRONICS Ltd 7 March 1974 [7 March 1973] 11225/73 Heading H4K A storage arrangement for repeated dialling a multi-digit number comprises a first recirculating register adapted to store the digits of said number, a second recirculating register having a number of bit positions equal to the number of digit locations in the first register and an excess bit position which can be selectively inserted into its recirculation loops to displace the single marker bit it contains to a position marking the next digit to be transmitted, and means operative subsequent to the read-out of all the digits to repeatedly displace the marker bit until it again marks the first digit. The dialler may generate multi-frequency or impulse type dial signals. The arrangement shown is formed as an integrated circuit employing IGFET's and is controlled by a push-button array and a punched card reader employing light sensitive semi-conductors. Binary coded digits if they persist for a time determined by timer T1 are gated at G4 to G7 via a code verifier and converter 15 into the first recirculating register 1A to 1D with the first digit to be transmitted in alignment with a marker bit in the second recirculating register 4. During transmission the digits are read out one by one to a counter B1 to B4 counted down by clock pulses also controlling a frequency dividing arrangement 17 producing impulses at 0. As each digit is transmitted the marking bit normally recirculated via gate G15 is recirculated via gate G16 to be aligned with the next digit. When all digits have been transmitted the marking bit is repeatedly recirculated until the marking bit and the first digit again appear together at the output of the recirculating registers. An additional recirculating register section 1E stores a 1 bit indication of the interdigit pause duration causing one of two predetermined counts to be inserted by circuit 16 into the counter B1 to B4 between each digit transmission under control of a bi-stable B8 which inhibits impulse transmission during these periods.

Title: Improvements relating to sheets of thermoplastic material having a porous or cellular structure
Inventor: LAMPARD EDWARD HENRY ARTHUR
IPC: C08J11/06
Filed: 1955-04-19
Abstract: A heat insulating, porous or cellular material comprises randomly arranged pieces of thermoplastic film welded together to form a sheet of irregular surface.  A thermoplastic film may be welded to one surface of the sheet.  The small pieces of film are randomly distributed, e.g. on a rigid perforated or porous horizontal support, to form a layer many times the thickness of the pieces, the layer is heated by radiant heat until the pieces are soft and adhesive, and by suddenly causing an air stream to pass through the heated layer, e.g. by applying suction to the rear of the perforated support, the pieces are welded together.  A continuous film may be sucked down to become welded on to the upper surface of the sheet during or subsequent to formation of the sheet.  The sheet may be formed continuously by using a travelling perforated or porous belt, e.g. of wire gauze, to carry the layer of pieces of film first under a heater and later over a vacuum box.  The thermoplastic material of the film may be a plasticized cellulose ester or ether such as the acetate, propionate, butyrate, acetate-propionate, acetate-butyrate, or ethyl cellulose, or a synthetic resin such as polystyrene, a copolymer of vinyl chloride with vinyl acetate, vinylidene chloride, or methacrylonitrile, polythene, polyhexamethylene adipamide, or polyethylene terephthalate.  The pieces of thermoplastic film may be mixed with fibres such as cotton, regenerated cellulose, or cellulose acetate spinning waste, thermoplastic material in flake form, small fragments of fabric of thermoplastic material, or small pieces of regenerated cellulose foil.  To assist adhesion, the material may be wetted with a plasticiser, solvent, potential solvent, or a liquid having a softening effect at the vacuum forming temperature, e.g. water or aqueous solutions of high boiling solvents or plasticizers such as diethylene glycol diacetate or triacetin; alternatively a thermoplastic adhesive such as polyvinyl acetate may be used.  The product may simulate snow or ice for Christmas decorations, or may be made from coloured pieces of film.  Specification 758,036, [Group XVI], is referred to.

Abstract: 801,207. Cooking stoves. HILLEBRAND, E. D. April 20, 1955 [Oct. 25, 1954], No. 11437/55 Class 126 [Also in Groups XIII and XXIX] In a cooking stove, a settable thermostatic control device for a heater or burner heating a heat-conductive cooking utensil is connected to a temperature-sensitive element having a flat upper heatconducting surface and resiliently mounted so that the surface presses upwardly against the utensil, the mounting including a vertically-movable member and a swivel allowing a limited tilting movement of the surface with respect to the member so that it is maintained in contact with the utensil. A heat-sensitive element enclosed in a head 30 is mounted on a pillar 31 supported in a bracket 58 and pressed upwardly by a spring 51 fixed at one end and pressing against the bottom of the pillar 31 at the other end. A contact cap 40 is tiltably secured on a bulb 35 in the head 30 by a skirt 45 and the upward bias of the pillar 31 maintains the cap 40 in contact with the underside of a griddle 21 heated by a gas burner 22. The pillar 31 is centrally arranged within the burner so that overheating of the head 30 is prevented by the secondary air supply to the burner. The heat sensitive element controls the gas supply through a valve (see Group XXIX), arranged so that the thermostaticallycontrolled temperature may be adjusted, or the burner may be controlled manually, at which setting the thermostat is inoperative except in the case of serious overheating Ridges 21a on the underside of the griddle protect the head 30 from the burner flames. The griddle 21 may be replaced by a normal pan support 76, Fig. 10, which carries a central shield 77 to protect the head 30 from direct contact with the flames and from the effect of draughts.
